JNFN S Bluetooth Balance BMS Board 7S to 16S 40 A Peak 100 A for Li-ion LiFePO4 LTO and Na-ion Yellow for E-bikes and Scooters
You already have the maximum available quantity in your cart.
The JNFN balance BMS board is designed for managing and protecting the battery of an e-bike or electric scooter. It is intended for batteries configured in 7S to 16S, meaning with 7 to 16 cells connected in series. The module is equipped with Bluetooth connectivity and a cell balancing function. The continuous current rating of the board is 40 A, and it can temporarily handle a peak of up to 100 A. The yellow board with mounting brackets and clearly labelled connectors can be easily placed into the battery box.
- Range 7S to 16S: the board is intended for batteries with 7 to 16 cells connected in series, allowing it to be used for various voltage configurations of e-bike or scooter batteries.
- Current 40 A and peak 100 A: the continuous current rating of the module is 40 A, and the board can temporarily handle a peak current of 100 A. Before installation, compare both values with the motor and controller's current draw.
- Supported cell types: the board is designed for batteries with Li-ion, LiFePO4, LTO and Na-ion cells, making it suitable for multiple types of battery packs.
- Bluetooth: wireless connectivity allows communication with the board without the need to connect a cable.
- Cell balancing: the balancing function equalises the voltage between individual cells of the battery.
- UART and SW port: connection point labelled UART and SW for data communication and additional connections.
- NTC T1 and T2 inputs: used for connecting temperature sensors to monitor the battery's temperature.
- Cell connectors: two connectors labelled B- and B+ are used to connect wires to individual cells.
- Power wires: the blue wire B- and the black wire C- ensure power connection. The colour coding of the wires helps prevent confusion during installation.
- Mounting brackets: brackets with holes on both sides of the board allow for secure fastening in the battery box.
- Design: the board has a yellow casing with the JNFN brand printed on it.

- 1x JNFN balance BMS board 7S to 16S 40 A
The JNFN balance BMS board is intended for building or repairing the battery of an e-bike and electric scooter with 7 to 16 series cells. It offers continuous current of 40 A with a peak of 100 A and supports Li-ion, LiFePO4, LTO and Na-ion cells. Thanks to the cell balancing function, the voltage of individual cells is equalised, and Bluetooth allows for wireless connection to the board. The inputs for NTC temperature sensors and the UART port expand the connection options. Before installation, ensure that the number and type of cells and the current draw match the specifications of the board.
